Title: Improved control system for variable speed power transmission mechanism
IPC: F16H61/02
Filed: 1953-06-16
Abstract: 742,552. Hydraulic brakes; control systems. GENERAL MOTORS CORPORATION. June 16, 1953 [June 25, 1952], No. 16497/53. Class 103 (1). [Also in Groups XXIV and XXIX] Two fluid servomotors 240, 300, for operating ratio selecting band brakes of a vehicle changespeed gear, not shown, are described. The first of these, 240, is pressure applied and spring and pressure released. Apply pressure from a line 100 leads to a lower chamber 246, containing a piston 243, and thence through a line 116, an overrun control valve 27 and line 116a to a separate chamber 249 beneath an upper piston 244. The connected pistons 243, 244 are thus both pressure loaded upwards to apply the brake, not shown, through their common piston rod in opposition to a single spring 251. To release the brake during a shift in ratio in the gear (see Group XXIV), the apply pressure in the line 100 remains on, and release pressure is fed from a line 111 to a chamber 247 above the lower piston 243, and thence through the hollow piston rod to a chamber 250 above the upper piston 244. Release pressure 111 also acts on the overrun control valve 27, raising the latter to exhaust at 260, the line 116a, and engaging chamber 249 beneath the upper piston 244 only, whereupon downward pressure overcomes the upward (on the lower piston only) and disengagement ensues. During normal engagement additional torque-regulated compensating pressure, fed through a line 109 acts upwards in a chamber 248 to augment engaging pressure. The brake servo 300 applies the brake by springs acting leftwards on pistons 303, 306 on a common piston-rod, and assisted by compensating pressure in the line 109 acting on the front piston 303 only. To disengage, pressure in a line 104 is applied to release chambers 308, 311 acting rightwards on both pistons. To re-engage, this line 104 is exhausted but whilst exhaust from the front chamber 31 is unrestricted, that from the rear 308 is restricted at 312 for gradual brake application, unless a manual selector valve 18 (see Group XXIV) has been set in a low range position, feeding pressure to a line 102 which opens an auxiliary exhaust valve 313, permit unrestricted exhaust from the rear chamber 308 also, through a branch line 104b. Specifications 522,881, [Group XXIV], 728,461 and 742,570, [Group XXIV], are referred to.

Class 125 (ii) Containers 8 to be filled are carried on a conveyer belt 2 towards a liquid vessel 1 and, when they reach an orifice 7 they contact a switch 13 which energizes a solenoid 9 to raise a ball-valve 11 in guides 12 to allow liquid to flow for a predetermined time controlled by an electronic or other timer started by the movement of the rod 10 of the ball 9 and, on stopping, de-energizing the solenoid 9. The switch 13 also stops the conveyer 2. The vessel 1 has a weir 4 maintaining a constant head above the valve 11 and defining a chamber containing a ball cock 3 and an impeller 6 urging the liquid under the weir. The vessel 1 may be heated or cooled and may include a resister, the change in value of which due to temperature alters the period of timer 14 in order to compensate for the change in viscosity of the liquid. The vessel 1 may have more than one controlled orifice 7 or a plurality of vessels 1 which may contain different liquids may be provided.

Abstract: 129,289. Ford, H. C. July 3, 1918, [Convention date]. Time alarms.-A signal is given after an interval slightly less than the time of flight of a projectile from a gun, to warn the spotter or other observer that the moment of impact is at hand. A disk 15, rotated once a minute by clockwork, has a circle' of sixty pins 22, gripped frictionally by a coiled spring 24. When one of the pins 22 is pressed down, as shown in Fig. 5, it eventually tilts a lever 20, which releases the striking mechanism of a mechanical bell or closes an electric bell circuit. At the moment when the gun is fired, a rotatable arm 39, which has previously been set to an angular position corresponding to the range or the elevation of the gun, is depressed so as to push down one of the pins 22, which operates the bell after an interval corresponding to the preliminary setting of the arm 39. The depressed pin is restored to its normal position by a cam 27. The apparatus is mounted in a watertight casing, with external means for winding and starting or stopping the clockwork, for rotating and depressing the setting arm, and for silencing the alarm.

Abstract: 1,190,885. Controlling binary fluid mixtures. EUROPEAN ATOMIC ENERGY COMMUNITY. April 8, 1968 [April 12, 1967], No. 16704/68. Heading G1N. [Also in Division G3] The ratio of the constituents of a binary fluid mixture is maintained constant by automatically regulating the flow-rate of one fluid, and maintaining a constant pressure difference between the two flow lines. As shown Fig. 1, two gases to be mixed in a desired ratio are fed from containers 1, 2 to a mixing nozzle 14, the resulting mixture being analyzed at 11 to produce a signal indicated at 12 and used to adjust a valve 13 controlling the flow from container 1. The measured and desired ratios are set up on variable resistors comprising arms of a D.C. bridge circuit, whose unbalance current controls valve 13. The pressure difference between the flow lines 3, 4 is sensed by a manometer 9 associated with an electrical transducer 10 and is automatically maintained constant by controlling a valve 19, bleeding pressure from the subsidiary line 4, or additional control of valve 13.

Abstract: 1,237,636. Electron beam focusing apparatus. WELDING INSTITUTE. 24 March, 1970 [31 March, 1969], No. 16767/69. Heading H1D. A magnetic lens for focusing an electron welding beam of a diameter greater than 10 mm. comprises a coil 13, Fig. 1, which is unshrouded over an internal length S which is at least equal to the diameter D so that the coil produces a radial field to deflect the electrons towards a focus and an increase in the current through the coil produces a decrease in diameter of the beam emerging from the lens. The coil may be unshrouded or may be shrouded by a mild steel tube 13 as shown in Fig. 1, and with a 100 mA 30 kV beam the focal length may be varied between 19 and 300 mm. (Fig. 2, not shown).

The set o independently rotatable elements 470, Fig. 1 having consecutive-number printing devices 564 565, and counting wheel 566 is mounted on a common shaft 544, which is adapted to be first moved endwise and then rotated to turn all the shafts 561, 562, 563 of the elements 470. The end of the shaft 544 is provided with a squared recess 632, Fig. 2, to receive a key or wrench and the shaft is fitted with a pin 633 normally engag ing a notch in a fixed sleeve or collar 634 on the side frame of the machine. A set of pinions 642 Fig. 4, fast on sleeves 641 loose on the shaft 544 engage pinions 643, Fig. 3, fast on the shafts o the numbering and counting devices. The shaft 544 is first moved endwise against the resistance of a spring 635, Fig. 3 at its right-hand end, anc clutch members 639 fast thereon enter notches 640 m the pinion sleeves 641, so that all the pinions turn together when the shaft 544 is rotated. The shafts 561, 562, 563, have square-sided notches 645, Fig. 1, to engage spring pawls (not shown) carried bv the various member wheels to turn them to zero in a known manner. The pinions 642 receive a slight axial movement against the resistance of springs 653 before the shaft 544 is rotated, so as to disengage holes 652 in the pinions from pins 651, which are carried by the end plates 541 of the elements and normally serve to main tain the pinions in effective connection with the elements. The return of the pin 633 into the notch in the collar 634, Fig. 2, indicates to the operator that the zeroizing operation is completed. The counter 621, Fig. 2, actuated at each issue of any ticket, as described in the above-mentioned Specification, is also zeroized with the consecutive numbering devices by the engagement of a pinion similar to the pinidn 642 with a pinion 644 on the shaft of this counter. A counter 655, Figs. 2 and 5, of the Veeder type, actuated through a cam 658 driven from the pinion 644, registers the number of times the devices have been zeroized.
